The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

System.ArgumentNullException: Value cannot be null - when using SetValue

Asked by GLComputing in Microsoft Programming, Microsoft Visual C#.Net, .NET Framework 2.x

Tags: .net framework SetValue

Trying to use the SetValue function to set data in a field via an SDK (see code below).

oppF  and oppF2 are not null because they return a field name.  I also tried those commented statements but still throw the same error. What am I doing wrong here?

I get this error:
System.ArgumentNullException: Value cannot be null.
Parameter name: format
    at System.String.Format(IFormatProvider provider, String format, Object[] args)
    at System.String.Format(String format, Object arg0, Object arg1)
    at Act.Framework.Opportunities.Opportunity.OpportunityFieldCollection.SetData(MutableEntityColumn column, Object data)
    at Act.Framework.MutableEntities.MutableEntity.FieldCollection.set_Item(String name, FieldNameType fieldNameType, Object value)

Would appreciate any suggestions to find the cause...
